. 9 Claims.

This invention relates to a wick for a liquid fuel trimmer and haszforone :of its objects the provision of a construction of wick which willpermit circulation of the fuel under -and about the same and preventuneven distribution of the :fuel in the wick groove.

Another object of the'invention is theprovision of a woven wick with itsinterwoven strands so arranged that they will provide projectingportions to support the wick above the bottom of the groove when restingon its edge along the wick groove in the burner base.

Another object of the invention is the provision of a. Woven wick withsome of the picks of weft strands projecting beyond the edge of the warpstrands and forming loops which will support the body of the wick whenrested upon these loops and permit free circulation of the fuel aboutthe wick.

A still further object of the invention is a provision of a wick formedof strands of asbestos having a stiffening core such as wire or thelike, which wick will have portions at intervals extended beyond theedge of the wick to support the the body of the wick in the burner.

With these and other objects in view, the invention consists of certainnovel features of construction, as will be more fully described, andparticularly pointed out in the appended claims.

In the accompanying drawing:

Fig. 1 is a side elevation partly in section of a portion of a burnershowing two of my improved wicks positioned therein.

Fig. 2 is a. view in elevation of the fabric Wick showing the projectingedge portions.

Fig. 3 is an enlarged view of one of the strands which go to form thewick illustrating its stiffening core.

Fig. 4 is a bottom plan view of the wick in its usual circular form.

Fig. 5 is an elevation of a fragmental portion of a modified form ofwick.

It is found in the use of wicks for oil burners that a wick which restsin the channel or cup frequently obstructs the free flow of the fuelabout the groove in which the Wick rests which causes uneven burning anda-formation of carbon at certain points in the burner, and in order thatthe flow will not be obstructed by the wick I provide a means forsupporting the body of the wick above the bottom of the wick channelwhich means is a part integral with the body of the wick, and thefollowing is a detailed description of the present embodiment of thisinvention illussame and permit free circulation of fuel about tratingthe preferred means by which these advantageous results may beaccomplished.

With reference to the drawing I 0 designates a burner "base having awickgroove I therein in which there is positioned a wick 12 in each of 6these grooves. This wick preferably consists of warp strands 13 extendedlengthwise of the wick with which there is interwoven a filling strand14 of the same material. Each :pick of filling extends outwardly as atiliifto provide :a loopalthough the arrangement may be such that analternate or a less number of picks may extend out to provide loop I5 ofthis construction, it being only necessary to provide a sufficientnumber of loops to support the body of the wick when in its heavieststate when soaked with oil.

Each of the strands which go to make up the warp and weft consist of awire core 16 about which there are twisted the fibers ll of asbestos orsome similar noncombustible material which 20 will absorb oil, and bycapillary attraction cause it to feed throughout the body l8 of thewick.

Weft strands which are stifiened in this manner cause the loops to be ofsuflicient strength so that these loops will support the body I 8 of thewick and hold it spaced above the bottom 19 of the wick grooves H thatthe liquid or gas in the fuel burner may circulate freely about the wickbeneath the same and prevent clogging or uneven distribution of the fuelthroughout the burner.

The wick is woven on a narrow fabric loom in extended lengths which arereeled and dispensed by cutting from the reel a desired quantity such asa length sufficient to provide an annular or ring shape formation asillustrated at 20 in Fig. 4.

While I have specified that asbestos is twisted about the wire strandsforming a stiff core any similar strands may be provided with or withouta stiff core so long as they will support the body of the wick andpermit free circulation of the liquid about the wick and below the same.

While I have shown my formation along one edge it may extend along bothedges if desired.

The foregoing description is directed solely towards the constructionillustrated, but I desire it to be understood that I reserve theprivilege of resorting to all the mechanical changes to which the deviceis susceptible, the invention being defined and limited only by theterms of the appended claims.

I claim:

1. A wick for a liquid fuel burner comprising a body formed ofintermeshing strands containing asbestos and some stiffening materialsuch as wire with some of the strands extending beyond 55 the body inspaced formation to leave openings substantially the size of the strandsbetween them.

2. A wick for a liquid fuel burner comprising a body formed of warpstrands and weft strands with certain of the weft strands extending inloops beyond the edge of the warps to form supporting projections andbeing sufficiently stiff to support themselves beyond the edge of thebody.

3. A wick for a liquid fuel burner comprising a body formed of warpstrands and weft strands formed of asbestos and wire with certain of theweft strands extending in spaced loops beyond the edge of the warps toform supporting projections.

4. A wick for a liquid fuel burner comprising a body formed of warpstrands containing asbestos and weft strands formed of asbestos and wirewith certain of the weft strands extending in spaced loops beyond theedge of the warps to form supporting projections on one edge.

5. A wick for a liquid fuel burner comprising a body formed throughoutof closely interwoven longitudinal and lateral strands of absorbentmaterial each having its own core of stiffening wire, some of saidlateral strands along one edge extending beyond the longitudinal strandsa distance greater than the thickness of one of the strands and spacedapart a distance to leave free passage between them of oil or gas whenthe wick is supported on these extending strands.

6. A wick for a liquid fuel burner comprising a body formed ofrelatively closely interwoven strands with some of the strands extendingbeyond the body in relatively loose or spaced formation along one edgeto leave openings of substantially the size of the strands between themand being sufficiently stiff to support themselves beyond the edge ofthe body.

'7. A wick for a liquid fuel burner comprising a body formed ofrelatively closely interwoven stiff strands with some of these stiffstrands extending beyond the body in relatively loose or spacedformation along one edge to leave openings of substantially the size ofthe strands between them and being sufficiently stiff to supportthemselves beyond the edge of the body.

8. A wick for a liquid fuel burner comprising a body formed ofintermeshing strands containing asbestos with some of these strandsextending beyond the body in spaced formation to leave openings ofsubstantially the size of the strands between them and beingsufficiently stiff to sup port themselves beyond the edge of the body.

9. A wick for a liquid fuel burner comprising a body formed of warpstrands and weft strands
